` 2 claims- (c1. 12e-16) The invention relatesV toa'loose-leafgfiling index or device and more especially to a visible, adjustable and loose-leaf filing index.

The primary object ,of the invention, is the provision of an index or device of this-character, wherein a loosefleaf for a binder carries holders, these being adaptable icr receiving and making visible items upon separate sheets, cards orthe like, these being readily changeable andrso constructed than an individual item may expose one or more lines for receiving written or otherwise impressed data freely' accessible, thereby assuring a handy system of iiling. c

Another object of the vinvention the proV vision of an index or device of this character,

wherein new items can be lled withoutthe necessity of removing or reling any of those items held in the device, the index being in pocket form and all items visible so thatl individual :filings do not have to be handled, thereby saving time in making reference thereto and preventing Wear and tear in the handling with the ,result that the records iiled are maintained neatand clean.

A further object of the invention ,is the Drovision of an index or device of thischaracter, wherein a series of cards or others items of memoranda is removablyheld andrarrangedin a. manner that the memoranda noted or items may be added to or removed from time to time or' substitution had at any point without -d-isturbing the general classication asA setv up. in the index or device and any selected memorandum or item can be examined without requiring the handling individually thereof or the turning of pages for locating such memorandum or item as is generally required in book'records.

A still further object of the invention is the provision of an index or device of this' character, wherein the setup thereof renders it compact, conveniently accessible, assuring the handling of items with dispatch and with minimum labor on the part of a user, the index or device being susceptible of expansion for increasing filings and avoiding misplacement of items, and providing a ready reference to selected or all of the items held thereby.

A still further object of the invention is the provision of an index or device of this character, which is simple in construction, novel in its make-up, thoroughly reliable and eicient in operation, convenient in the handling thereof, assuring ready and easy reference to lings, strong, durable, and inexpensive to manufacture and install.

With these and other objects in View, the in- 55 of the leaf being vention consists in the features of construction, combination and arrangement of parts as` will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the preferred and modified forms of embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1y is an elevation partly in section of an index or device constructed in accordance with the invention.

Figure 1 is a sectional view taken on theline 2 2 o f Figure 1 looking inthe direction .of the arrows.

Figure 3 is a sectional View of the loose. leaf alone taken on the line 3-3 of Figure 1 looking in the direction of the arrows.

Figure 4 is an elevation of one of the holders associated with the index or device.

Figure 5 is a View similar to Figure 4 looking toward the opposite side thereof.

, Figure 6 is a detail plan view of a blank form from which the holder, as constructed in Figures Y 4 and 5, is made.

Figure 7 is a sectional View on the line l-l of Figure 4 looking in the direction of the arrows,

Similar reference characters indicate corre spending parts throughout the several views in the drawings.

Referring to the drawings in detail, particularly Figures 1 to 7, inclusive, A designates one of a series of loose leaves for a binder (not show-n) and B a holder for a card, memorandum .or other record bearing mediums, respectively, for association with each other and constituting the present invention.

The conveniences of the loose-leaf book as well as the card system have become thoroughly established, being required. for present day methods of business enterprises that the same be used conjunctively, and the joined use and the construction of each being hereinafter fully described.

Each loose leaf A is preferably formed from relatively stiff brous or like sheets of material, these including the outside sheets I 0 and Il, respectively, and an intermediate sheet l2, being joined in any suitable manner face to face and in matched relation to each other. The outside sheets are plaited adjacent the opposite edges of the leaf A and in parallel relation to each other to provide retaining folds I3, which extend throughout the area of the leaf A in one direction and the said folds I3 next to the lowermost edge cut and folded diagonally at I4 to provide stop tongues I5, these being formed from the inner plies of the plaits and united to the face thereof of the sections I and II next thereto while the plaits or folds I3 at the uppermost edge of the sheet are free for admission of the holder B for slidable interiitting with the said folds I3 of the leaf A in a manner presently described. p

The folds I3 are at opposite sides of the leaf A and coextendin spaced parallel relation to each other from the uppermost edge of the leaf to a point close to the lowermost edge thereof. It is preferable that the leaf A be perforated at intervals following one side edge thereof but removed therefrom and said perforations reinforced by eyelets I6 so that a plurality of leaves may be attached in a temporary binder (not shown) and of any desirable form, the eyelets I6 accommodating the loose-leaf fastening medium (not shown) as may be employed for looseleaf binding in a binder.

The leaf A at the free turning edge thereof opposite to the edge havingassociated therewith the eyelets carriesa marker tab II for indexing indicia, as is lcommon in indexing leaves of a book, in this instance the indicia being the letter A, as at I8.

The holder B for amemorandum slip, card or the like, as, for example, at I9, comprises a racking frontal portion and an intertting backing portion 2I, respectively, the latter portion being provided with a tab extension 22 while the portion 20 is provided with a leg or prop 23. This holder B is made from a single blank of sheet material 24 having reversely tapered ends, one constituting the tab extension 22 and the other the leg or prop 23. The blank is foldable along crease lines 25,26 and 2l, respectively, for producing the portions 20 and 2I, respectively, the pull extension 22 and leg or prop 23, respectively. The -blank 24 at opposite longer edges has the diagonal slits 28 meeting fold lines 29 which are parallel with each other longitudinally of the said blank and inwardly of the side edges thereof so that when the blank is folded first up along line 28-in Figure 6 and then these side edges are foldedvinwardly over the portion extending between theV lines and 2l there is produced racking plaits or folds 30 forwardly of the frontal portion 20 and stop lips 3Iat the lowermost ends of the plaits or folds 30, these plaits and lips being inset with relation to runner wings 32 which are projected beyond the said folds or plaits 30 at opposite ends of the backing portion 2I for slidably fitting the plaits or folds I3 of the leaf A. These plaits or folds I3 are in overlapping relation to the wings 32 when the holder is fitted to the said leaf. The lips 3l are turned on crease lines 33 and fixed to the backing portion 2I so that the folds or plaits 30 will pocket the card I9 when engaged therewith for carriage by the frontal portion 20 of said holder. The leg or prop 23 extends beneath the stop lips 3I when fastened to the portion 2| so that on the interfitting of a plurality -of holders sandwiched between the frontal and backing portions 20 and 2| the cards I9 pocketed in the respective holders so interfltted will be stepped vertically with the uppermost portions visibly exposed, one above the other, when the said holders are carried upon -the leaf A. The frontal portion is susceptible of vertical swing following the crease line 25 so that the card I9 in each holder will have its outermost face freely exposable for a major extent of the said cards excepting the end portions pocketed by the plaits or folds 30 of the holder and in this manner easy reference and visibility selectively of the 'cards is obtainable.

The exposed uppermost portions of the cards have present thereon suitable identifying indicia, as-at 34, enabling ready selective reference to the cards racked in the index or device. It is preferable to have the leg or prop 23 attached permanently-to the backing portion 2| so as to stiffen such flap forV the lifting function thereof in the interiitting of the holders one within the other for indexing of memorandum slips, cards or the like in the association of these holders with the leaf A.

What is claimed is:

1. A card holder 'for a loose-leaf filing index, comprising a 'cut and folded body formed from a single sheet of relatively stiff fibrous material providing a backing portion and a racking frontal l portion forwardly off and swingable on a horizontal axis relative to said backing portion, a leg extended below the axis of the swingable frontal portion, racking pleats at opposite ends of the frontal portion and disposed forwardly thereof, runner wings at opposite ends of the ybacking portion, and lips turned inwardly and upwardly rearwardly of the backing portion for effecting stops atfthe lower ends of the pleats.

2. A card holder for a loose-leaf filingindex, comprising a cut and folded body formed from a single sheet of relatively stiff fibrous material providing a backing portion and a racking frontal portion forwardly of and swingable on a horizontal axis relative to said backing'portion, a leg extended below the axis of the swingable frontal portion, racking pleats at opposite ends of the frontal portion and disposed forwardly thereof, runner wings at opposite ends of the backing portion, lips turned inwardly and upwardly rearwardly of the backing portion for effecting stops at the lower ends of the pleats, and an extension rising from the backing portion above the uppermost edge ofthe frontal portion.`
